Courses Plus Student 94,596 PointsHi Reinaldo,
Your only issue is the method name. getElementsByTagName()
Elements should be plural.

Courses Plus Student 7,538 PointsWow just an s throw the whole code off? JavaScript is really sensitive.

Courses Plus Student 94,596 PointsYes, certain things like method or property names need to be typed exactly.
One thing you can do to help you remember whether you should use Element or Elements in the method name is to ask yourself whether that method could return multiple elements or not.
getElementById doesn't have an 's' because that method can only ever return 1 element since id's are unique on the page.
By contrast, getElementsByTagName returns a collection of elements so the plural form of Element is used indicating you might get back more than one depending on the html.

Courses Plus Student 7,538 PointsMakes sense since is this case there were an array of spans.
